Is sharpening stone finally worth it?
“Worth it” is tough. I think the skill semi-kicks kitten , you precast it and then use it mid-fight as an insta-cast condi clear. However as often as I take it I never do it with ease of mind. It’s competing against an awful lot of good utilities like GoE, GoT, PM, LR, SoS, SoR, etc.
If you’re taking WK, I would likely wind up taking it. Almost certainly not without that trait though.
